FILE - In this Sept. 15, 2010, file photo, combines, costing several hundred thousand dollars each, harvest a field during a corn harvesting demonstration at the Husker Harvest Days fair, in Grand Island, Neb. A program that puts billions of dollars in the pockets of farmers whether or not they plant a crop may disappear with hardly a protest from farm groups and the politicians who look out for their interests. The Senate is expected to begin debate the week of June 4, 2012, on a five-year farm and food aid bill that would save $9.3 billion by ending direct payments to farmers and replacing them with subsidized insurance programs for when the weather turns bad or prices go south.
